This script will show a menu on startup making you choose what speed you want. It can be 15m/s(default), 20m/s, 30m/s, 40m/s, or Ultra, which is 50m/s!

I derived it from a sample script which is classes.lua but made it into this instead.

NOTE: You can choose it to be a LUA file. Just opn a LUA file with notepad, delete all contents, and paste the script below, and save it. And you can rename it to [the name of the map you want the scipt activated at].lua and put it at the maps folder. Then, you can run CS2D and then the map where you named it also after the LUA file (say, you renamed the LUA file to as_snow.lua, then run the map as_snow), and then it will be activated! (In that map only, thoguh.)
